GUT-OUT Box Filed Aug. 2'?, 1919 2 sheens-sheet 2 @j 15 a 5"' z www@ which Correspond to analogous parts described above in connection with Figs. 1 to 5 are indicated by the same reference characters. and such parts are the elements 25 and 27 forming a channel-shaped member which is thus open at its front. In this instance the contact member indicated at 45 and .is inwardly bowed, instead of outwardly as is the with the contact member 29. Also the contact member 45 is provided with outwardly slanting menr bers L16` 4.6 and is provided at one end with a flange 4T. A plug 48 is shown in Fig. 7 inserted between the back 25 and the contact member (4 5, the thickness of the plug being slightly greater than the distance between the back 25 and Contact member so that when the plug is inserted in the recep` tacle it will force the contact member 4:3 slightly outwardly. The member 46 is normally substantially in contact with a front strip 37 so that when the member 4J is forced outwardly it will be yieldingly held inwardly at its lower end as well as at its upper end in perfect contact with the plug 48 throughout the length of the flat member 31. In this form of the invention t-he plug 48 is provided with a single lead 52 and the receptacle may be con nected with a lead or with a. fuse-supporting clip similar to the clip 23 above described.

The invention is not limited in its broader phases to the exact details of construction shown in the drawings and described above` but the invention also includes such changes and modifications as lie within the spirit and scope of the appended claims.

IVe claim:

1. In a cut-out box. a support of electrical insulation material, a pair of spaced brackets mounted on the support, spring contact members secured at one end to the brackets respectively7 and bowed toward each other,`the other end of the contact members being adapted to loosely engage the brackets so as to yieldingly hold said other end against outward movement, and a fuse-supporting clip mounted on one of the brackets.

2. In a cut-ont box. a support of electrical insulation material, a pair of spaced brackets mounted on the support. spring contact members secured to the brackets respectively, and a fuse-supporting clip mounted on one of the brackets.

3. In a cut-out box, a casing having an opening. a plate of electrical insulation fastened in the opening and provided with an opening therethrough, a pair of spaced brackets fastened at one end to the plate and projecting inwardly therefrom, electric contact members mounted on the adjacent faces of the brackets. and fuse-supporting members fastened to the brackets and projecting from the outer faces of the brackets. f

4. In a cut-out box, a casing having an opening, a plate of electrical insulatir'm fastened in the opening and providedwith an opening therethrough,` a pair of spaced brackets fastened at one end to the plate and projecting inwardly therefrom, electric contact members mounted on the adjacent faces of the brackets, fuse-supporting members fastened to the brackets and projecting from the outer faces of the brackets, a second plate of electrical insulation mounted in the casing. bus bars fastened to the opposite sides of the second plate, and fuse-supporting members fastened to the bus bars in alinement with the fuse-supporting members on the brackets.

5. In a plug receptacle, an electrical insulating member having an opening, a channel-shaped member forming a back and side flanges and mounted on the insulating member with the open side of the channel shaped member turned toward the opening in the insulating member, and an electric spring contact member fastened at one end to the inner face of the back of the channel-shaped member between the flanges and having its opposite end free and adapted to loosely engage the back, said contact member being *bowed away from said back to engage a plug inserted in the opening in the insulating member, and means to fasten the opposite ends of the channel-shaped member to a support.

6. In a cut-ont box, a casing having an opening, a plate of electrical insulation closing the opening and provided with an opening therethrough, and a pair of spaced brackets fastened at one end to the plate and projecting inwardly therefrom and providing electric contacts on the adjacent faces of the brackets for engagement with an electric plug inserted in the opening of the plate.

7. In a cut-out box, a casing having an opening, a plate of electrical insulating material closing the opening and provided with openings therethrough, a second plate of electrical insulating material in vertical relat-ion to the first plate, electric contacts connected with the first plate on opposite sides of the openings therein, and partitions of electrical insulating materialextending transversely of the plates and between said plates.
